Martha Stewart is now relying on the kindness of convicts to make herself pretty.

Once a board member for cosmetics giant Revlon, the guru of good living borrowed makeup last weekend from a fellow prisoner at a federal lockup in West Virginia, one inmate told the Post.

And one could bet it wasn’t Chanel.

Stewart, the inmate said, borrowed the cosmetics to make herself more presentable for her daughter, Alexis, who came to visit the disgraced domestic diva during her first days behind bars at the Federal Prison Camp in rural Alderson, W.Va.

Also last weekend, Stewart was frequently interrupted by many people visiting other inmates at the prison, the source added.

Contrary to previous reports that Martha was sharing a cottage with several prisoners, the inmate said Stewart was actually given her own cottage.

The inmate also said the federal lockup is seriously cracking down on inmates speaking to the media about Stewart. She said that at least three have already been disciplined, including one who was transferred to another prison.

Dawn Zobel, a spokeswoman for FPC-Alderson, said the prison does not discuss disciplinary procedures.

Stewart – also known as prisoner No. 55170-054 – is serving five months at the prison for women. She was found guilty by a jury of lying to authorities about events surrounding her suspicious 2001 sale of stock in the biotech firm ImClone Systems Inc., just before its price plunged.
